Final answer:
The speed of sound is affected by the type and temperature of the medium.
Step-by-step explanation:
The speed of sound in a medium depends on two main factors: the type of medium and the temperature of the medium.
The type of medium affects the speed of sound because different materials have different densities and elastic properties. For example, sound travels faster in solids than in liquids, and faster in liquids than in gases.
The temperature of the medium also affects the speed of sound. In general, as the temperature increases, the speed of sound in a medium increases as well. This is because at higher temperatures, the particles in the medium vibrate more rapidly, allowing sound waves to travel faster.
